Glazing with a Stepped Pane Element Cemented to a Frame

ABSTRACT

A window or door glazing has a stepped pane element ( 3 ) which is adhesively bonded all the way around to a frame ( 10 ), for example the frame ( 10 ) of a window sash. In this case, two regions of adhesive compound are provided, firstly in the region of the smaller pane ( 2 ) of the stepped pane element ( 3 ), and secondly on the inside of the protruding edge of the larger glass pane ( 1 ) of the stepped pane element ( 3 ).

The invention relates to glazing with an insulating glass pane which is fixed in a frame.

In known glazing of the initially named type, insulating glass panes are held in the frame by retaining strips or the like without there being a non-positive connection between the frame and insulating glass pane so that it essentially contributes nothing to the stability of the frame.

The object of the invention is to devise glazing in which the insulating glass pane used in the glazing stabilizes the frame.

The object is achieved as claimed in the invention with glazing which has the features of claim 1.

Preferred and advantageous embodiments of the glazing as claimed in the invention are the subject matter of the dependent claims.

Because in the glazing as claimed in the invention an insulating glass pane in the form of a stepped pane element is used (stepped pane elements are insulating glass panes in which one of the two glass panes is larger in at least one direction than the other glass pane, especially the larger glass pane projects over the other glass pane on all four edges) which is connected to the frame, the insulating glass pane contributes to the stability of the glazing.

In particular this is advantageous in glazing of windows because the window wings are stabilized when the glazing is done as claimed in the invention. By joining the insulating glass pane made as a stepped pane element to the frame of the window wing, it is stabilized and withstands the forces (inherent weight) acting in the direction of its diagonal and torsional forces when the opening is opened, especially when it is tilted.

Within the framework of the invention it is preferred if the stepped pane element is cemented peripherally to the frame of the window wing.

In this case it is especially advantageous if the larger glass pane of the stepped pane element is cemented to the frame like the smaller pane.

The invention is advantageous especially in conjunction with a movable window wing (swivel window, pivot-hung window, etc.) because even with an unstable construction of the frame of the window wing it is stabilized such that warping of the window wing which occurs under the action of its own weight in the diagonal is prevented, like twisting of the window wing.

Another advantage arises in the production of an exemplary, preferred embodiment of the glazing as claimed in the invention. By simply applying a cement mass to the frame, for example of the window wing, and in the sealing mass joint in the stepped pane element, which can be done without special precision, the stepped pane element then need be: simply inserted, for example horizontally, into the frame (of the window wing). The sealing masses swell under the edge of the smaller glass pane of the stepped pane element over the entire periphery and also peripherally under the glass edge. After setting of the sealing masses the stepped pane element is fixed on the frame and movement between the stepped pane element and the frame is thus rendered impossible. The sealing mass on the edge joint of the stepped pane element is also pressed flat against the front edge of the (window) frame and in doing so distributed two-dimensionally, the sealing mass being distributed under the edge joint of the stepped pane element and on the front surface of the (window) frame after setting stabilizes the frame and the entire window wing against twisting (warping).

In order to cover the visible edges of the cement mass which in any case run uncontrolled and which do not damage the quality of the glazing, but which should not to be visible to the onlooker, the glass edge of the large glass pane of the stepped pane element in the region of the edge joint can be covered with for example fired, high-strength enamel. For the onlooker there is a thus a glazing unit with a glass frame formed in any color.

The invention can be used for glazing with any frame. Preferably the glazing as claimed in the invention is used in movable frames, such as the frames of window and door wings.

Several details and features of the invention will become apparent from the following description of one preferred embodiment of glazing as claimed in the invention using the example of a window.

FIG. 1 shows partially in a section a window with glazing as claimed in the invention and

FIG. 2 shows the window wings for a segment of its production.

A window as is shown in FIG. 1 has a frame 11 which is installed for example in a building, and a casement 10. Glazing in the form of a stepped pane element 3 is attached to the casement 10. The stepped pane element 3 has two glass panes 1 and 2, a peripherally running spacer 4 and a sealing mass (seal) which is placed outside the spacer 4. Furthermore, on the glass pane 1 of the stepped pane element 3 which is made larger, on its side facing the smaller pane 2 of the stepped pane element 3 in the edge area, therefore essentially in the region outside of the spacer 4, a preferably opaque layer 5 which is made for example colored, for example an enamel strip, is applied.

Between the frame 10 of the window wing and the stepped pane element 3, in particular between the smaller glass pane 2 of the stepped pane element 3, there is a seal 7 in the form of a sealing strip profile which prevents penetration of dirt or water from the room side.

On the frame 11 of the window there is a similar sealing strip 8 in the form of a sealing profile which prevents penetration of dirt or water from the outside.

The stepped pane element 3 is connected to the frame 10 of the window wing by cementing, in the embodiment with two cement masses 6 and 9.

The cement mass 6 is located mainly in the projecting region of the larger glass pane 1 of the stepped pane element 3 and connects it to the surface of the frame 10 of the window wing, which surface points toward the frame 11 of the window.

The second cement mass 9 is located in the region of the smaller pane 2 and is especially arranged such that it surrounds the inner edge of the stepped pane element 3 formed by the edge of the smaller glass pane 2 (therefore is made essentially L-shaped in cross section).

It should be pointed out that the cement mass 6 also surrounds the edge of the frame 10 of the window wing, therefore can be made essentially L-shaped.

Because the stepped pane element 3 is cemented around the periphery to the frame 10 of the window wing, it is advantageously stabilized as described initially.

To install the stepped pane element 3 in a frame 10 of a window wing, it is possible to proceed as explained in FIG. 2. Two (strands of) cement masses 6 and 9 are applied, a cement mass 9 being placed in the interior corner in the frame 10 of the window wing. The other cement mass 6 is placed in the inner corner of the step of the stepped pane element 3. The amount of cement masses 6 and 9 in place is such that the cement masses 6 and 9 are distributed as is shown in FIG. 1 when the stepped pane element 3 and frame 10 of the window wing are joined. After curing of the cement masses 6 and 9, a fixed joint between the stepped pane element 3 and frame 10 of the window wing is achieved so that (window) glazing as claimed in the invention with its advantages is present.

The invention is not limited to use in windows, but can also be used for doors or for glazing of fixed components.

In summary, one embodiment of the invention can be described as follows.
